LOCKING-DEVICE FOR WINDOW-SASHES.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed March 25, 1920. Serial No. 368,782.

To all whom t may concern:

Be it known that I, JAMES R. CLAY, a citizen of the United States, and aresident of Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Locking Devices forvWindow-Sashes, of which the iollowing is a specification.

The invention relates to means for locking the upper and lower sashes ofa window stationary either to prevent the rattling thereof or theopening of either sash from without.

My invention resides in a novel locking device of wedge type to beremovably en-l tered between the face of one side of the lower sashandits retaining strip and having a pivoted or hinged member to beengaged with the adjacent face of the correspending side of the uppersash, said wedge preventing the raising or rattling of the lower sashand said member preventing the lowering or rattling of the upper sash.The device of my invention serves both as a lock to safeguard the windowagainst intrusion from `without and as means to prevent the usualrattling of window sashes by winds, and said device isequally eii'ectualwhether both sashes are entirely closed or both are partly open and alsowhen one sash is wholly closed and the other partly open. The pivoted orhinged member of the device is adjustable as to length so as to adaptthe device to the varying separations of the vertical planes of theupper and lower sashes of windows that may exist. I also preterably soconstruct my lock or catch that it is reversible and therefore adaptedfor application to either the right hand side or the left handside of awindow sash.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being. had t0 the accompanyingdrawings, in which:

Figure 1 is a vertical transverse section, partly broken away, through apair of window sashes and their easement equipped with the lockingdevice of my invention, both sashes being shown in closed position andthe section being on the dotted line 1 1 of Fig. 2;

Fig. 2 is a horizontal section through the same taken on the dotted line2 2 of Fig. 1;

Fig. `3 is a detached top view, partly in section, oi2 my lockingdevice; n

Flg. 4 is a front elevation, partly in section, of the same;

Fig. 5 is a side elevation, partly broken away, of the same, and

Fig. 6 is a iront elevation, partly in section, corresponding with Fig.4c, showing a modiiication in the construction of one detail of thedevice.

In the drawings 10 designates a portion ot a window easement or framingof usual or any suitable construction, 11 the lower window sash, 12 theupper window sash, 13 the usual sash cord for the lower sash, 14; theusual strip separating the sashes, and 15 the usual retaining strip forlthe lower sash, all of said parts remainingunchanged so t'ar as myinvention is concerned.

My invention resides in a novel removable lock or catch to be appliedtothe window framing and sashes, and consists, in the preferredconstruction, of a wedge-member 16 having a iat outer face 17, apivotedor hinged link member' 18, an adjustable sleeve 19 and a lock-nut 20 forbinding the sleeve 19 in its adjusted positions.

rilhe wedge member 16 has on its inner tace the outwardly inclineddiverging wedge faces 21, 22, at whose apex is secured or formed abearing 23 for the link member 18. The wedge member 16 may be in oneintegral piece, as shown, and the link member 18 is constructed from anintegral rod fashioned to form a journal 24. to be mounted in thebearing 23 and two side arms 25, 25, which are substantially paralleland one of which, 26, is longer than the other and screw-threaded toreceive the sleeve 19, which is elongated in form and has an internallythreaded bore to engage the threaded portion of said arm 26. The arm 25is made short so as to be free of the separating strip 14, as shown inFig. 2, and when the device is positioned for use said arm is applied atthe outer side of the sash cord 13, as shown. wardly, as at 27, so thatthe side of the sleeve 19 may clear the separating strip 121 when theouter end of said sleeve is turned against the upper sash 12, as shownin Figs. 1 and 2. Upon the inner threaded portion ot' the arm 26 islocated the lock-nut 20, and this The arm 26 is bent or offset out` nutis screwed against the inner end 0f the sleeve 19 in every adjustment ofsaid sleeve for binding the sleeve rigidly in position. The sleeve 19preferably has a ribbed outer surface, as shown, for convenience inrotating said sleeve by hand during the adjustment thereof on the arm26.

In Figs. 1 and 2 l illustrate the lock as applied to the right hand sideof a window, and when, so applied, the wedge surface 22 of the member 16is pressed with firmness downwardly between the face of the right handside of the lower sash 11 and its retaining strip 15, and the linlrmember 18 is turned. over toward the` upper sash 12, the arm 25 beinginserted back of the sash-cord 13 and theouter end ofthe sleeve 19 beingwedged against the upper sash 12 so as to bind said sash rmly inposition and against rattling. The wedge member 16 serves to bind thelower sash 11 against rattling movement. lf'the combined lengthof thearm 26 and sleeve 19` shonldbe soigreat as .to prevent the. same from`acting as a prop wedging tightly againstk the upper sash 12, the sleeve19 must be adjusted inwardly on the arm 264 so as to decrease saidlength and per mit the arm to stand at such angle that it mayeffectually bind the upper sash iirmly against itsframing. After thedevice-of my invention has been positioned, it will lock the lower sashagainst upward movement and the upper sash against downward movenientandalso prevent rattling movement of both sashes. j

Should it be desired 'topapply the lock. to

the left hand side of a window, the device will be turned over andapplied as before, the

vwedge surface 21 then being forced downwardly between the lower sashandits adjacent retaining strip. Except for rendering the lock applicablefor both the right and. left hand sides of `a window, the member 16would only require one wedge sur- .thisr aids in such engagement thereofwith the upper sashi as to prevent downward movement of the sash, whilenot preventing upward movement. thereof.

The bearing 23 may be formed from a piece of` metal and securedtothemember 16, as shown, or saidbearing may be formed in.-

tegrally with the wedge member, as shown in Fig. 6, wherein, being amodication in recense part l number the wedge member 28 and the bearing29, this bearing serving to receive the journal 24C and therebypivotally connect the link member 18 with said wedge member.

The lock of my invention is composed of durable,casilymanufactured,assembled and adjusted parts and may be handled as a unit.

What l claim as my invention and desire to secureby Letters-Patent, is-

1'. A window sash lock of the character described, comprising a wedgemember for insertion between-thelower sash and its retaining strip, anda link menibenhinged to said wedgemember adapted to. serve as a propagainst the upperv sash.
